LABEL DESCRIPTION
DoS Attack
Enable DoS Protection Enable this to protect against DoS attacks. The LTE7460-M608 will drop sessions that
surpass maximum thresholds.
SYN Flood This is the rate of new TCP half-open sessions per second that causes the firewall to
start deleting half-open sessions. When the rate of new connection attempts rises
above this number, the LTE7460-M608 deletes half-open sessions as required to
accommodate new connection attempts.
Echo Storm This is the rate of new Echo Request half-open sessions per second that causes the
firewall to start deleting half-open sessions. When the rate of new connection
attempts rises above this number, the LTE7460-M608 deletes half-open sessions as
required to accommodate new connection attempts.
ICMP Flood This is the rate of new ICMP Request (other than Echo) half-open sessions per second
that causes the firewall to start deleting half-open sessions. When the rate of new
connection attempts rises above this number, the LTE7460-M608 deletes half-open
sessions as required to accommodate new connection attempts.
